Introduction; Performance Changes; Machine Size Setting Changes; Electronic Modules - Fisher & Paykel GWL08US Service Manual

This Service Supplement contains information on the Product Specifications, Diagnostic Mode and
the Detailed Fault Codes. For all other Service and Option Adjustment information please refer to
your GWL03 Service Manual part number 426348.
Note: The water temperature adjustment in the Option Adjustment mode is only available on
model GWL03. Model GWL08 has 5 preset temperatures which are factory set and are non
adjustable.
The detailed fault codes in this service supplement can also be used for Model GWL03 Smart
Drive Washing Machines.

PERFORMANCE CHANGES

The introduction of model GWL08 sees changes to the way the Smart Drive senses and reacts to
what is going on in the basket.
The Smart Drive  Washing machines has two load sensing methods to ensure the right wash
action is used for the type and size of the wash load.
• LSD - Load Sensing Detection is used to continually sense the load and automatically adjust
the agitation profiles to suit the wash load. It is also used to determine when a maximum
capacity profile needs to be used. If the machine is operating on the high water level, regular
cycle, with a very large heavy load, then the load sensing detection will activate the Maximum
Capacity Profile.
• MCP - Maximum Capacity Profile is in the high water level regular cycle only. It is clearly
noticeable as the machine will stop agitating and restart with a perceivably different profile. It
usually occurs 3-6 minutes into the wash and will, of course, only occur if the machine is
extremely heavily loaded.

MACHINE SIZE SETTING CHANGES

With model GWL08 we have made changes to the way the size setting is set into the Motor
Controller Module's memory. There is no longer a size switch in the Display Module and the Size
Setting has to be manually entered. See Machine Size Setting Mode on page 5. Failure to do this
will result in the machine faulting to detailed fault code 9.

ELECTRONIC MODULES

Electronic Modules are not inter-changeable between models.
The different modules for the different models can be identified by their colour. GWL03 modules
are green and the latest GWL08 modules are yellow.
It is important not to mix the different colored modules as there is different sensing between the
models and you will find that the washing machine will not work. It will automatically display a
fault code and beep if the modules have been mismatched.
